Gowrishankar, the managing director of a company in Madras, receives a letter from his old friend Pattabi informing him about the death of their teacher, Indumathi. On reading the letter, Gowri becomes nostalgic and recollects his past.

In childhood, Gowri, Pattabi and Raghupathy are close friends and study at a village school. The three friends try to explore sex through a prostitute, but run away immediately after reaching her house. Pattabi likes the girl who visits his house and starts spending time with her. Gowri likes the new teacher Indu and dreams of living with her, despite the wide age gap. Raghupathy looks for excitement through his friends.

Gowri’s dreams are shattered when Indu’s fiance arrives. Indu spends more time with her fiancé, which upsets Gowri. Pattabi and Gowri fight on trivial issues, but stay united due to Raghupathy. The boys get influenced by the postmaster, who indulges in sexual activities outside the village. They also get tempted to smoke like Indu’s fiancé to experience it. All their excitement ends when Raghupathy drowns in the village pond when the three go swimming. When Gowri visits Indu, she is also in tears and shares her pain with him.

In the present, Gowri is filled with tears in his eyes after recollecting his childhood, his friend’s demise and the time spent with his friends.
